Intelligent carrier aggregation for multiservice user equipment

Abstract

The technology described herein is directed towards a carrier aggregation system for a user equipment requesting simultaneous voice and data sessions. In one example, a classification model determines whether carrier aggregation, if used in conjunction with voice quality data, will likely result in acceptable or unacceptable voice quality for a user equipment, based on dynamic user equipment-related and cell-related input data. If voice quality is deemed acceptable by the model, carrier aggregation is allowed to be used simultaneously (and activated if not in use) with voice service. If voice quality is deemed unacceptable, carrier aggregation is not allowed to be used simultaneously with voice service, (and released if currently in use). Monitoring is performed to evaluate whether subsequent conditions (updated input data) change, such as if estimated voice quality degrades such that carrier aggregation is no longer allowed to continue when both carrier aggregation and voice are otherwise in use.
